Frequently Asked Questions

Common questions about PlexMCP.

General​

What is PlexMCP?​

PlexMCP is a unified gateway for Model Context Protocol (MCP) servers. It lets you manage, monitor, and secure access to multiple MCPs through a single dashboard and API.

What is MCP?​

Model Context Protocol (MCP) is a standard for AI agents to interact with tools and resources. MCPs expose functions (tools), data (resources), and templates (prompts) that AI assistants like Claude can use.

Is PlexMCP open source?​

Yes! PlexMCP is open source. You can self-host it or use our managed cloud service. See oss.plexmcp.com for self-hosting documentation.

How is PlexMCP different from using MCPs directly?​

PlexMCP adds:

  • Unified authentication: One API key for all MCPs
  • Management dashboard: Visual interface for configuration
  • Analytics: Usage tracking and monitoring
  • Team collaboration: Multi-user access with roles
  • Security: Rate limiting, access controls, audit logs

Getting Started​

How do I get started?​

  1. Create an account
  2. Add your first MCP
  3. Generate an API key

Do I need to install anything?​

For the cloud service, no installation is needed. Just sign up and start using the API.

  • Custom MCPs you build

Do you offer audit logs?​

Audit logs are available on Team and Enterprise plans, with configurable retention.

Troubleshooting​

My MCP shows as "Unhealthy"​

  1. Check if your MCP server is running
  2. Verify the endpoint URL is correct
  3. Test the MCP directly with curl
  4. Check your MCP server logs

API returns "Invalid API Key"​

  1. Verify the complete key was copied
  2. Check the key hasn't been revoked
  3. Ensure it hasn't expired
  4. Confirm you're using Bearer prefix

Requests are slow​

  1. Check MCP server performance
  2. Verify network connectivity
  3. Consider using a closer region
  4. Contact support if issue persists

Rate limited (429 errors)​

  1. Implement exponential backoff
  2. Check Retry-After header
  3. Consider upgrading your plan
  4. Optimize request patterns
